Gf enjoys busting my balls

I (M19) met my gf (F19) a little over a year ago. We’re both religious and are abstaining from any kind of sexual before marriage, including masturbating. I had never truly been busted before meeting her.

A few months ago, Sara (not her actual name) accidentally hit me in the balls when we were just walking and after that started getting more interested in playing around with her new toys.

While we avoid anything too crazy, we’re both also extremely attracted to each other, so we make out and get steamy pretty frequently, while never finishing each other off. When we make out in bed, sometimes she’ll slide her knee up and crush my nuts into my body for fun. She loves watching my reactions when she does it and loves how it turns me on. She hasn’t admitted it, but I suspect she also likes the control it gives her over me.

Since we’re saving ourselves for marriage, we both always have some level of underlayers on (her minimum is a bra and shorts, my minimum is just shorts) and neither of us can use our hands on each other’s nether regions.

However, one of the most unfortunate parts of our situation is that Sara barely has to do anything to make me throb for her, which frequently leads to me getting blue balls. It’s hot in a way, when my nuts are just aching for her and it reminds me of what she does to me, but it’s also really painful. But when she crushes my nuts, it stops my throbbing and brings me back down to normal. A lot of the time, this saves me from getting blue balls, which is great. Ofc it also saves me from blowing my load in my shorts, which has happened at least 8 times thanks to her.

Besides, Sara is a great ball buster. She’ll analyze my reactions to see what gets me going the most. A lot of the time I’ll wrap my legs around her and let her ram her thigh up into my crotch. She likes to give me 3-5 quick knees and then a long one that she keeps up, crushing my manhood against it for 5-10 seconds straight, before moving her leg back down.

My nuts are also able to roll back up inside my body, which happens a lot from her crushing. She loves feeling my nuts rolling around, and especially when she forces them back up inside me. Just last week, she had me lay down on my bed while she sat down at the other end, in between my outstretched legs. I was throbbing, so my dick was up and out of the way and my large nuts hung down low in the front of my shorts. Then, out of nowhere, she reached out her feet and started pressing them into my sack. She played around with them, occasionally reaching her foot up to stroke my dick through my shorts to tease me before going back to busting me again.

Then, she pushed the base of her feet against the bottom of my sack, forcing both of my balls up and inside my body. Then she pushed down with her toes where my nuts has gone and pushed them back down into my sack. They got squished going in and out, and yet it felt so good. She got into a rhythm and kept doing it for about five minutes and I can’t wait for her to do it again.

Now pretty much every time we make out and I get rock hard she crushes my nuts to bring me back down to normal, which just turns me on more. It also can lead my balls to be black and blue when she’s done with me, but that just turns me on even more.

Please let me know any questions you have or suggestions for what she can do going forward! I love talking about this stuff with people who are a lot more experienced than me.
